This issue was first reported by users on 13.04 and has lasted at least to 15.10. I am presently struggling with it on Ubuntu 14.04. On this release the "gsettings set" workaround does not work, neither does logging out and logging back in. There are a number of other workarounds discussed at AskUbuntu:
